The man claiming he invented bitcoin, Craig Wright, has filed for copyright of the original Satoshi Nakamoto whitepaper.
The Australian entrepreneur claimed to be Nakamoto, the creator of the cryptocurrency, back in 2016.
He was granted copyright registration over both effective April 2019, according to a GoinGeek press release.
"Wright wrote most of version 0.1 of the Bitcoin client software, and the registration covers the portions he authored," CoinGeek said.
At the time of publishing, bitcoin was worth around $8,000, up from $5,300 a month ago.
